Figure 6. SBT3.3 expression poises SA-mediated defense genes for enhanced activation.

Figure 6

(A) RT-qPCR of PR-1, WRKY6, WRKY53 and WRKY55 transcript levels following inoculation with PsDC3000 in Col-0 and SBT3.3OEX1 plants. Data represent the mean ± SD; n = 3 replicates. (B) Comparative level of histone H3 Lys4 trimethylation (H3K4me3) and histone H3 K9 acetylation (H3K9ac) on the PR-1, WRKY6 and WRKY53 gene promoters as present in leaf samples from Col-0, SBT3.3OEX1 and nrpd2 plants. Data are standardized for Col-0 histone modification levels. Data represent the mean ± SD; n = 3 biological replicates. Expression was normalized to the expression of the constitutive ACT2 gene.
